industrial waste water discharged from the base paper production, iron and steel,

non-ferrous metallurgy, coal mining in the dry season, the total volume of wastewater

in the region accounts for about 15% of

river flow Bridge, papermaking wastewater with a pH from 8.4 to 9 and 4 mg NH4 / 1, high levels of organic matter, brown
